- a reset pulse 102 for initiating the electronic shutter function is applied during the vertical blanking interval 101 to reset the charges accumulated in the photosensitive elements 65.
- the reset pulse 102 serves as an integration start signal for an electronic shutter function, and at this moment the photosensitive elements 65 (both even-number and odd-number elements) start accumulating electric charges anew.
- a sweeping pulse 103 sweeps the unnecessary charges remaining in the vertical shift register 66 and with a lag time 108 after the reset pulse 102, signal charges are read out from the odd-number photosensitive elements 65 to the vertical shift register 66 by a first read pulse 106.
- the read signal charges are transferred to the storage region 62 by an odd-number transfer pulse 104.
- a sweeping pulse 103 sweeps the unnecessary charges remaining in the vertical shift register 66.
- a second read pulse 107 is applied so as to read signal charges from the even-number photosensitive elements 65 to the vertical shift register 66.
- the read signal charges are transferred to the storage region 62 by an even-number transfer pulse 105.

- a first reset pulse 112 is applied to the photosensitive elements 65 as shown in FIG. 11(b) to reset the charges previously accumulated in the photosensitive elements 65, which then starts accumulating charges anew. Then a sweep pulse 118 sweeps the unnecessary charges from the vertical shift register 66. Then, with a lag time 114 from the first reset pulse 112, a first read pulse 113 is applied so as to read signal charges from the odd-number photosensitive elements 65. The read signal charges are transferred to the storage region 62 by a transfer pulse 119 and, as a consequence, the picture signal for field A is outputted.
- a second reset pulse 115 resets the charges accumulated in the photosensitive elements 65, whereupon the photosensitive elements 65 start accumulating charges anew.
- a sweep pulse 118 sweeps the unnecessary charges in the vertical shift register 66.
- a second read pulse 116 is applied so as to read signal charges from the even-number photosensitive elements 65.
- the read signal charges are transferred to the storage region 62 by a transfer pulse 120 and, as a result, a picture signal for field B is outputted.
- the integrating time for photosensitive elements 65 for field A and that for field B can be freely set so that the luminance of each field can be adjusted independently of the other. Furthermore, by equalizing the lag time 114 and lag time 117, any disparity in luminance between adjacent scan lines can be eliminated so that a subject of homogeneous luminance can be displayed without a disparity in luminance between adjacent scan lines and, hence, a picture of high quality can be obtained.
- the same effect can be obtained by applying high-voltage pulses between the image sensor semiconductor substrate and the photosensitive elements 65 as said first reset pulse and second reset pulse.
- the second driving method described above for electronic shutter function is not only applicable to the solid state image sensor shown in FIG. 6 but can be equally applied to the prior art solid state image sensor shown in FIG. 1 or any solid state image sensor of the FIT structure, invariably with the same result.
